Patented Mar. 10, 1953 UNITED STATES PATENT OFFICE HOSE REEL James A. Jensen, Haverford, Pa., assignor to Philadelphia Valve Company, Philadelphia, Pa., a corporation of Pennsylvania Application July 24, 1948, Serial No. 40,519 2 Claims. (01. 299-78) This invention relates to hose reels. More specifically, it is concerned with hose reels of t e type disclosed in U. S. Patent No. 2,348,692 granted to me on May 9, 1944, intended for use on commercial vehicles such as are ordinarily employed in the delivery of gasoline, fuel oils and other liquid commodities. In reels of the kind referred to, the liquid is conducted through a stationary fitting connected to a conduit which leads from a supply tank on the vehicle, and which is in direct communication with a hollow trunnion of the reel having a radial branch whereto one end of the hoseis attached.

One of the aims of my invention is to insure, in such a reel structure, against fluid leakage between the revolving trunnion and the stationary fitting without imposition of appreciable resistance to the free turning of the reel. This objective is realized in practice as hereinafter more fully set forth, through provision of an anti-friction bearing having an internal circumferential recess for lodgment of a ring gasket with means for automatically expanding it both circumferentially and laterally so as to bear snugly against the contiguous ends of the trunnion and the stationary fitting.

A further aim or my invention is to so construct a reel structure of the indicated sort, that the bearing can be quickly and easily disassembled in part for convenience of replacing the gasket when it has become Worn.

Another object is to provide for ready lubrication of the relatively movable parts of the reel bearing as well as for the sealing gasket.

In a reel structure having the foregoing attributes and wherein the stationary fitting is in the form of an elbow, it is a further aim of my invention to provide for securing said fitting in various positions around the bearing for convenience of connecting the conduit which may be disposed at difierent angles depending upon the location of the reel in respect to the tank on the vehicle.

Fig. 1 is a View in side elevation of a hose reel conveniently embodying my present invention.

Fig. 2 is an end elevation of the reel as seen from the right of Fig. 1.

Figs. 3 and 4 are fragmentary views in section taken as indicated respectively by the angled arrows III-III and IV-IV in Fig. 1.

The organization herein illustrated is generally similar to that disclosed in my patent hereinbefore referred to, in that it comprises a horizontal axis reel 5 which is rotatively supported by standards 6 and I. Bolted to one side of the reel is a sprocket ring 8 which, through a chain 9, is connected to a sprocket pinion II] on a transverse shaft I I having rotative support in a mountthe horizontal branch 2|, see Fig. 3, constitutesv the other trunnion of the reel and is journalled in a bearing 23 at the top of standard 6. To the radial branch 25 of elbow 20 is bolted another; elbow 26 whereof the outer end extends through a clearance opening 21 in the core drum 28 of reel 5. As shown in Fig. 1, the outer end of elbow 26 is disposed tangentially of the drum 28 and is provided with a coupling 29 for connection of the hose 30 which is normally wound upon the reel. The trunnion branch 2|-of the elbow 20 is in axial alignment with the outlet end of a terminal fitting 3| of a pipe or conduit 32, which fitting is likewise in the form of an elbow. The fitting is stationarily supported, in a manner later on explained, with its inner end in threaded engagement with conduit 32 which extends from a tank or other supply source of the liquid (not shown) on the delivery truck.

In accordance with my present invention, I employ a bearing 23 of the ball type with its inner race 35, see Fig. 4, held in position between an external circumferential stop shoulder 36 on the trunnion branch 2| of elbow 2i! and a split retaining ring 31 sprung into an external circumferential groove 38 in said branch. The outer race 39 of bearing 23 is engaged in an internal circumferential recess 40 of an apertured disk 4| having an axial boss 42 which engages into the circular opening 43 of a bracket 45 bolted to the top of the standard 6. A retaining disk 46, abutted against disk 4|, serves, in conjunction with the latter, to hold outer race 39 of the bearing 23 in place. The outer face of the disk 46 is flush with the end of the trunnion branch 2| of elbow 20 as shown, and interposed between it and the corresponding face of the flange 41 of elbow 3| is an annular spacing member 48. It is to be noted that the internal diameter of the spacing annulus is made somewhat less than the bores of the elbow 20 of fitting 3|, and lodged in the circumferential recess thus formed is a sealing gasket 49 of rubber or other compressible material having an internal V groove in which a split spring ring 50 is disposed. By the action of this spring ring 50, the gasket 49 is expanded circumferentially and laterally for maintenance of a fluid tight seal between the end of the rotating trunnion branch 2| of elbow 20 and the face of flange 41 of the stationary fitting 3|. As best shown in Fig. 4, the parts 4|, 46 and 48 are clamped, between the bracket 45' and the flange 41 of fitting 3| by four headed screw bolts 5| whereof the shanks pass through aligning holes in said parts. noted from Fig. 1 that bracket 45 is provided with eight holes 5|a, the other parts 4|, 46, 41 and 38 having but four. Due to this; arrangement, the fitting 3| can be set in difierentpositions. around the bearing in Fig. 1 to suit the conduit 32 which may extend at different angles depending uponv the location of the reel relative to the tank on the vehicle.

For the lubrication of bearing 23, spacing mem- 1363:4815 provided with. a radial oil ingress duct. 52 which, through a crosswise passage 53, communicates with annular grooves 54 the opposite faces of said: member. From one of the grooves 54 the oil passes by way of small ports 55 annulus: 46- directly tothe balls of bearing 23. Due to the construction. just described, supply of oil to: the bearingv 2.3 andthegasketAS- will be assured even if spacing member- 48 should be re-- versed, in position in being assembled with the:

other parts of the structure.

thus described my invention, I. claim:

1, In. ahose reel structure, a. reel having a hollow tubular trunnion with a radial branch for connection theretoof one-end oi the hose; asupporting. bracket with a clearance opening for projection of the trunnion therethrough; a. retaining plate for a. ball bearing which the trunnion isjournalled, said plate. being abutted against the outer face of. the bracket and being flush with the end of the trunnion; a terminal fitting for a stationary pipe having an annular flange around its outlet end in coaxial relation. with the trunnion; a spacing annulus interposed It is to be between the outer face of the plate and the confronting face of the flange of the terminal fitting. the opening in said annulus being larger in diameter than the aligned flow passages in the trunnion and the fitting, with consequent formation of a concentric internal recess; a ring gasket of resilient material lodged in said recess; and headed securing elements with their shanks passing continuously through prelocated registering apertures in the bracket, in the bearing retaining plate, in the spacing annulus and in the flange of the pipe terminal fitting.

2. A hose reel structure according to claim 1, wherein, for the purpose of bearing lubrication the opposite facesv of the spacing annulus are provided with annular grooves which are connected; by a. crosswise passage in communication with a radial oil ingress duct extending to the periphery of said member and wherein ports through the retaining plate in line with the grooveso-f" the spacing annulus lead to the balls of the bearing.
